IMPROVEMENT IN BREWERS BOILERS.

Specification forming part of Letters Patent No. 221,702, dated November 18, 1879, application tiled March 19, 1879.

To all whom it may concern Be it known that I, FREDERICK WILLIAM SOHROEDER, of the city, county, and State of New York, have invented a new and useful Improvement in Brewers7 Boilers, of which the center ofthe boiler', so as to heat all parts of the contents at the same moment.

The invention will be understood by reference to the accompanying drawings, of whichi Figure 1 is a sectional elevation of the improved boiler; and Fig. 2 is a sectional plan of the same, taken on a line, x x, of Fig. 1.

The boiler consists of two concentric, or nearly concentric,shells, A B, made of any suitable sheet metal, and united together by stays a, so as to form a chamber, C, between them.

A steam-pipe, D, is placed vertically in the center of the boiler, and to this is attached a series of steam-chambers, F,vwhieh are secured in place by means of angle-iron flanges d, secured to the pipe. These steam-chambers are formed ot' two disks, e and e', of sheet metal, which are unit-ed at their peripheries by riveting, and from thence to the central.

e., from the periphery down toward the centerso as to allow the condensation to run back into the steam-pipe.

Within each of the chambers F the steampipeD will have numerous perforations, d2, for permitting steam from the said pipe to enter and fill the said chamber F.

The vertical steam-pipe D will receive its steam from the inlet steam-pipe D', and return its condensation and spent steam to the steam boiler through the return pipe D2. This same steam-pipe will supply steam to the chamber O by means of its connection at d', at th'e bottom of the said boilerA B, with the said chamber C, and the return steam-pipe D2 will connect with the outside shell of the boiler A B and conduct olf all the waste-steam and condensation.

The boiler A B will be provided with a suitable cover, G, which will be removably attached to the sides of the boiler.

There will be a masonry setting, H, surrounding and supporting the boiler, and acting to retain the heat.

After the beer-mixture is properly boiled, it will be drawn off through the dischargingpipe I and the shut-off cock I. After the beer-mixture is thus drawn oft", steam will be admitted to the chambers O and F, and the deposits remaining on top of the disks c and clinging to the insides of the boiler will be granulated and pulverized by this steam-heat, so that the introduction of fresh water will thoroughly wash out the said boiler and fit it for the next charge.

Having described my invention, I claiml. The double boiler A B, provided with a steam-tight cover, Gr, and a steam-chamber, C, surrounding the sides and bottom of the boiler, and combined with a vertical central steam-pipe, D, as and for the purpose set forth.

2. The steam-chambers F, formed of two sloping disks, e and c', united at their peripheries, as described, and combined with the supporting steam-pipe D and the surround- B, having an inclosed heating-chamber, C, ing boiler A B, as and for the purpose' setwith the heating-chambers F, and the comforth. mou steam-supply pipe D D', and the waste- 3. The detached steam-chambers F, formed pipe D2. with sloping top and bottom plates, e and e', FREDERICK WILLIAM SCHROEDER in combination with the central supporting and supplying steam-pipe, D, as and for the Witnesses: purpose set, forth.
